So I have a MD102LL/A (2.9GHz, 8GB RAM, 750GB HDD) that is recently water damaged. It can turn on, but it takes a moment and the Genius Bar told me it was likely the motherboard (recognizes battery & its charge but doesn't charge/turns off when unplugged). Other than that part and some keys not working, it seems to work just fine (recognizes hard drive, RAM appears to be intact, I believe Disk Drive works, etc). I think it originally cost something like $1499 at Apple. I'm considering selling it, would anyone be able to tell how much I can expect for it and where is the best place to sell?
